Abstract

Abstract : This study aimed to analyze the reliability and validity of the Vancouver Scar Scale (VSS) and the Withey score after syndactyly release. Over a 3-year period, 13 patients who underwent syndactyly release were evaluated. The mean age at the time of syndactyly release was 12 months (range, 8–18 months), and the mean follow-up period was 29 months (range, 17–52 months). We obtained hand photographs and finger motion videos and collected the satisfaction scores for hand function and cosmesis. Three clinicians evaluated the hand photographs and finger motion video of each patient twice using the VSS and the Withey score. The interobserver and intraobserver reliabilities of the VSS and Withey score were determined using intraclass correlation coefficients (ICCs). The validity of the VSS and Withey score was determined using Spearman's correlation test with the functional and cosmetic satisfaction score. The ICCs for the interobserver reliability of VSS were 0.31 and 0.39 for each measurement, and ICCs for the intraobserver reliability of VSS were 0.46, 0.51, and 0.54 for each observer. The ICCs for the interobserver reliability of the Withey score were 0.74 and 0.70, and the ICCs for the intraobserver reliability of the Withey score were 0.91, 0.74, and 0.96. The Withey score was significantly correlated with the satisfaction score for hand function and hand cosmesis, but the VSS was not. The VSS had poor interobserver reliability and fair intraobserver reliability, whereas the Withey score had good interobserver reliability and excellent intraobserver reliability based on photographic evaluation after syndactyly release.
